摘　　要：针对新疆某金铜矿地处高海拔、工业场地有限、地形复杂、环境敏感,选矿厂与尾矿库距离长、高差大,矿山上、下采区同时开采,自流和泵送共存的问题,为充分平衡井下充填与尾矿输送,实现矿山绿色开采,结合开拓系统,确立了矿山尾矿充填最优浓密方式,提出了尾矿输送与充填系统布置相协调的3种可行方案。从工艺流程、工程投资、运营成本、地表生态环境保护等多方面进行对比分析。结果表明:矿山最适合采取深锥浓密方案,充填站布置在地表2 800 m回风平硐+尾矿两级输送(方案一)在投资、运营费用、费用现值及可靠程度方面明显优于方案二和方案三,且系统可靠性高、便于管理。研究为同类型矿山尾矿输送及充填系统的建设提供了解决思路。A gold-copper mine in Xinjiang is located at a high altitude.The industrial site is limited,with complex terrain and a sensitive environment.The distance between the dressing plant and the tailings pond is long and the height difference is significant.Under the conditions of simultaneous mining of upper and lower mining areas and coexi-stence of self-flow and pumping,to fully balance underground filling and tailings conveying and achieve green mining of mines,the paper,based on the development system,established the optimal thickening method for mine tailings filling and proposed 3 feasible solutions for the coordination of tailings conveying and filling system layout,which are compared and analyzed from multiple aspects including process flow,engineering investment,operating costs,and surface environment protection.The results show that the mine is most suitable for the deep cone thickening scheme,and the filling station is arranged at the surface of 2800 m air return audit+two-stage tailings conveying(SchemeⅠ),which is obviously better than SchemeⅡandⅢin terms of investment,operating costs,present value cost,and reliabi-lity.Besides,the system has high reliability and is easy to manage.The research provides solutions for the construction of tailings conveying and filling systems of the same type of mine.
